                Value to describe the component can either be provided with <i>aria-labelledby</i> or <i>aria-label</i> props. The treeselect element has a <i>combobox</i> role in addition to <i>aria-haspopup</i> and <i>aria-expanded</i> attributes.
                The relation between the combobox and the popup is created with <i>aria-controls</i> that refers to the id of the popup.
            </p>
            <p>
                The popup list has an id that refers to the <i>aria-controls</i> attribute of the <i>combobox</i> element and uses <i>tree</i> as the role. Each list item has a <i>treeitem</i> role along with <i>aria-label</i>, <i>aria-selected</i>{' '}
                and <i>aria-expanded</i> attributes. In checkbox selection, <i>aria-checked</i> is used instead of <i>aria-selected</i>. Checkbox and toggle icons are hidden from screen readers as their parent element with <i>treeitem</i> role and
                attributes are used instead for readers and keyboard support. The container element of a treenode has the <i>group</i> role. The <i>aria-setsize</i>, <i>aria-posinset</i> and <i>aria-level</i> attributes are calculated implicitly and
                added to each treeitem.
            </p>

            <p>
                If filtering is enabled, <i>filterInputProps</i> can be defined to give <i>aria-*</i> props to the filter input element.
